Navigate the site

Locate resources for all Core topics using the drop-down menus or  link.

The menus are organised by topic, with the heading pages (e.g. Thermal concepts and Modelling gases) containing concise revision notes, images, top tips and flashcards. All of these pages are currently free with a Basic Subscription.

Sub-pages (e.g. Particle model (kinetic theory) and Boyle's law) contain videos to give you a more detailed understanding of the physics and a quiz for you to check your learning.

The Sitemap ensures that you are always no more than two clicks away from the content you want to see next.

• Coverage is based on the time you have spent on a page. The default time is set at 15 minutes, which will bring you to the IB's recommended learning hours overall.
• Self-assessment is for you to control. Use the sliding scale at the bottom of each page to remind yourself of what content you'd like to see again.
• Score is the most objective measure, based on your quiz result at the foot of the page. You can try these again and again to see if you're improving.
• 'My notes' is just that. You'll find a text box next to the self-assessment slider. Click to reveal your note-to-self.
